What I find weird, here, is that you put Beamer frames *inside* other Beamer
frames. I think that's the problem.

Why are you trying to do so?  What are you trying to achieve, structurally?

For me, setting =BEAMER_FRAME_LEVEL= to 0 means you can play with different
sectioning levels above your set of slides; but not that you can have slides
in slides...

Example:

--8<---------------cut here---------------start------------->8---
#+BEGIN_SRC org
* Intro (Section)

** Slide #1                                                         :B_frame:

** Slide #2                                                         :B_frame:

* Chapter 1 (Section)

** Problem (Sub-section)

** Slide #3                                                          :B_frame:

** Slide #4                                                          :B_frame:

** Solution (Sub-section)

** Slide #5                                                          :B_frame:

* Conclusion (Section)

** Slide #6                                                          :B_frame:
#+END_SRC
--8<---------------cut here---------------end--------------->8---

Here, you have the following TOC structure:

1. Intro
2. Chapter 1
   2.1 Problem
   2.2 Solution
3. Conclusion

and some slides that are placed at different structuring levels...

HTH,
  Seb
